PollCat NetLink User's Guide

1. Introduction
The PollCat NetLink Call Accounting Terminal is a highly
reliable, PBX data recorder designed for SMDR/CDR data
collection and alarm monitoring. Collected call records can be
retrieved via TCP/IP network, via FTP client, via modem, or by a
local PC connected directly to the NetLink unit.
In addition to storing call data, NetLink can also monitor call
records for suspicious phone activity or critical alarm conditions.
When an alarm is detected, the unit can immediately notify the
proper personnel by pager, modem, or SNMP trap. The NetLink
also provides secure access to connected serial devices such as
PBX maintenance ports or console/aux ports.
Network and Modem Access
All command functions, including data retrieval and unit
configuration, can be accessed via network or modem. When the
NetLink is installed in a TCP/IP environment, Telnet is used to
access the command mode. If out-of-band access is required, you
can also dial-up NetLink’s internal modem. Stored data can be
reliably retrieved using your terminal emulation program, an FTP
client or Zmodem protocol. Password protection and dialback
security prevent unauthorized access to control functions.
Nonvolatile Flash Memory
NetLink uses reliable, low-cost flash memory to store call records
and operating parameters. This eliminates the need to check and
replace depleted batteries. If power to the unit is lost or
interrupted, stored data can be retained indefinitely without
worrying about low or dead batteries. NetLink is available with
512 K to 64 Megabytes of internal memory. If more memory is
needed later, additional memory modules can be easily snapped
into place.
SNMP Traps
Alarm messages, memory full status, and a variety of other
conditions can be reported to your network manager via standard
SNMP traps. SNMP Traps can be used to provide notification
when an alarm event occurs, or to perform a wellness check at user
selected time intervals.
1-1

Three PBX Inputs
NetLink includes three separate data input ports; two PBX ports
and an Auxiliary Port. This allows the unit to collect data from
three different sources. The Auxiliary Port can be connected to a
third PBX, or other data generating device, or used to pass
commands to a connected device such as WTI’s RPB+ Remote
Power Boot Switch. Communication parameters can be
individually defined for each port. When the unit is polled, data
from the three ports can either be combined, or read separately.
Easy Firmware Upgrades
When program upgrades are available, there is no need to struggle
with EPROM installation. NetLink’s flash memory allows you to
upload the latest firmware revisions via modem or console port.
Disclaimer on Toll Fraud
We do not guarantee that if you use the NetLink, you will not
become the victim of toll fraud. We provide this device to assist
you in minimizing your exposure to such losses. By monitoring
call records as they are received, you can potentially catch calls
that should not be made before they escalate and cost you large
sums of money. However, responding to alarms and determining
what is fraud and abuse are still up to you. Western Telematic,
Incorporated assumes no responsibility for any losses due to
improper use of this product.
Typographic Conventions

3.2.5. Power Up Default (Sw8)
The Power Up Default allows the user to reset communication
parameters to default settings without entering Command Mode.
Note: If you have changed Set-Up Switches 1
through 5, and you wish to clear all menu selected
parameters, Switch 8 should be set in the UP
position. This will allow default parameters selected
by the Set-Up Switches to take effect when NetLink
is powered up.
When the Power Up Default is enabled, NetLink will reset the
following parameters after an interruption in power:
·Input Port Communication Parameters: The Baud rate for
PBX Ports A and B, and the AUX Port are set according to the
Set-Up Switches, rather than command selected parameters.
All three ports will be set at 7 bits, even parity, one stop bit.
·Console Port Communication Parameters: The Baud rate
will be set according to the Set-Up Switches. The Port will
also be set for 8 bits, no parity, one stop bit.
·Modem Port Communication Parameters: The port will be
set to 57600, 8 bits, no parity, one stop bit.
·Passwords: The Supervisor Password will default to
"SUPER". The User 1 Password will default to "SMDR". In
the default state, the User 2 Password is not defined.
CAUTION: If Set-Up Switch 8 is UP (enable
Power Up Default), and there is a loss of power,
port parameters will be set to the default values
selected by Set-Up Switches1-6.
If the Power Up Default is disabled (Sw8 = Down), when there is a
power interruption, NetLink will be configured according to the
parameters currently saved in flash memory.

3.3. Reset to Defaults
This procedure will reset the NetLink to the settings indicated by
the Set-Up switches, reset all menu selected parameters to factory
defaults, and clear the flash memory.
When the unit is shipped from the factory, defaults are reset and
the memory is cleared. However, if the NetLink has been
previously installed, or if you have changed switch settings, this
procedure should be performed. It is also recommended to reset
the unit after installing additional memory modules.
Notes:
·When this procedure is performed, all menu
defined parameters will be cleared. If the unit has
already been configured, parameter settings should
be saved (as described in Section 14.2), before
beginning this procedure.
·If the NetLink unit has the base 512K memory
option (no SIMMs), all stored data will be cleared.
If the unit has collected data, it is recommended to
retrieve stored data (as described in Section 15)
before beginning this procedure.
